摘要
随着网络技术的发展,各种威胁也愈演愈烈。局域网作为网络功能的基础单元,对它的安全进行保护具有重要的意义和研究价值。一种以BLP模型为基础的多级安全局域网系统从体系结构入手来研究计算机系统的安全问题。该系统以透明计算机系统为平台,引入考虑局域网内信息安全性的安全策略服务器与动态监控交换机设备,并在终端内嵌入终端监控模块与登录控制模块,实现了对局域网系统中各种行为的监控与管理。
With the development of computer network, there come a lot of security threats LAN is a basic unit of network functionality, and its security is very important and significant. A Multi-level Security Local Area Network System （MSLANS） based on BLP model is proposed, which with transparent computing system as the platform, conforms with the requirements of security infrastructure. By introducing the security policy server and dynamic monitoring switch into the system, and embedding modules into terminal computers to monitor the user＇ s operations and login procedures, the secure LAN system could thus accomplish the centralized control and protection of the operations within the terminal computers.
